What are current 15-year fixed mortgage rates in Texas?

Freddie Mac's Primary Mortgage Market Survey put the average 15-year fixed rate at 6.42% for the week ending September 24, 2026. The 30-year fixed averaged 7.03% the same week, so the shorter term carried about a 0.61% rate advantage. These are national survey averages for borrowers with strong credit; your quoted rate will differ.

Quick answer: a 15-year fixed mortgage locks one interest rate for 180 equal monthly payments, paying the loan off in half the time of a 30-year loan.

Why your rate may differ from the average

Lenders price your loan off your credit score, down payment, loan amount, property type, and whether the home is your primary residence. Rate locks are optional and time-limited, so a quoted rate is only real once it is locked in writing.

How do 15-year rates compare to 30-year rates?

Fifteen-year loans almost always price below 30-year loans because the lender's money is at risk for half as long. The trade-off shows up in the payment, not the rate. Rates shown are survey averages and subject to change without notice; APR on your loan will reflect your actual costs.

The payment trade-off

Because you repay the same balance in 180 payments instead of 360, the monthly principal and interest is higher on a 15-year loan even at a lower rate. What you get in return is faster equity, a shorter payoff, and far less total interest.

Total interest saved

Shorter terms crush total interest. In the worked example below, the 15-year borrower pays the loan off in half the time and spends roughly a third less in total payments, even though the monthly check is larger.

What does a 15-year fixed loan cost and require?

A 15-year conventional loan follows the same cost structure as other conventional mortgages: down payment, closing costs of roughly 2% to 5% of the loan amount in Texas, prepaid items like insurance and property taxes, and monthly principal and interest. If you put less than 20% down, expect private mortgage insurance (PMI) until you reach sufficient equity.

Must have

• A credit profile the lender can underwrite (see the FAQ on scores, including no-score options)
• Documented income and a debt-to-income ratio within program limits
• A down payment, which can be as low as 3% on some conventional programs
• A satisfactory appraisal on the home

May be required

• PMI if your down payment is under 20%
• Cash reserves for certain loan sizes or credit profiles
• A rate lock extension if your closing runs past the lock period

Is a 15-year fixed mortgage right for you?

A 15-year fixed loan fits borrowers whose income comfortably covers the higher payment and who value a guaranteed payoff date. If the payment would strain your budget, a 30-year loan with voluntary extra payments reaches a similar outcome with more flexibility.

The process, step by step

1. Check your numbers. Review your credit, monthly budget, and how the higher 15-year payment fits.
2. Get pre-approved. A pre-approval letter shows sellers you are a serious buyer and locks down your real price range.
3. Compare rate quotes. We gather 15-year quotes from multiple lenders and explain the trade-offs in plain English.
4. Lock your rate. Once you are comfortable, lock the rate in writing for a defined period.
5. Close and fund. Appraisal, underwriting, disclosures, and a Texas closing, typically about 30 days from contract.
